There are five major lessons from COP30. They are not the ones the climate community has highlighted, but they really matter and will shape the post-COP30 climate change negotiations.

First up is the realisation that it is no longer a European (and UK) game. The shifts in world political and economic power for the first time sidelined the Europeans. There was no UK “climate change leadership” to be taken seriously. It is India, China, Russia and the US that pulled the strings, whether present or not. Second, no major oil and gas producer or coal-burning nation wants to stop. Brazil set the tone: it announced that it wants to be the world’s fourth-largest oil producer, with drilling to start in the mouth of the Amazon. Third, no one wants to cut their carbon consumption, personally or nationally. The Brazilian carbon footprint includes the flights, the new road through the rainforest, the cruise liners for accommodation, as well as the commitment to its own fossil fuels. Fourth, the real action was on the bottom-up trade issues, notably the carbon border adjustment mechanism (CBAM) and the emerging coalition of the willing with the extension of carbon pricing. The fifth lesson is that the temperature is going to go on rising: 30 COPs so far haven’t made a dent in the carbon concentration in the atmosphere, and another 30 COPs probably won’t.
